Expensive but worth every penny 🎀✨ This serum has trillions of exosomes in it that promote hair growth as well as a reverse grey technology that helps restore the hair to its original pigment. This serum is insane for density. I still use the Monat serum in between this one since I’m growing my hair out but this one I use once every other day and always directly after washing 💕 LTKBeauty
